The wrap outer pretensioner 5 is a member for instantaneously winding up the looseness of the waist side seat belt and enhancing the restraining effect of the occupant when a strong impact is sensed at the time of collision.

［サイドシル１の構造］
図４に示すように、前記サイドシル１は、車室外側Ｗ２（車幅方向外側）のサイドボディアウタパネル６と、車室内側Ｗ１（車幅方向内側）のサイドシルインナパネル２と、サイドボディアウタパネル６とサイドシルインナパネル２の間に位置するサイドシルストレングス７とから成る。 [Structure of side sill 1]
As shown in FIG. 4, the side sill 1 includes a side body outer panel 6 on the vehicle exterior side W2 (vehicle width direction outside), a side sill inner panel 2 on the vehicle interior side W1 (vehicle width direction inside), and a side body outer panel 6. And side sill strength 7 located between the side sill inner panel 2.

前記サイドボディアウタパネル６とサイドシルストレングス７は車室内側Ｗ１に開口する断面ハット形状に形成され、サイドシルインナパネル２は車室外側Ｗ２に開口する断面ハット形状に形成されている。   The side body outer panel 6 and the side sill strength 7 are formed in a cross-sectional hat shape opening to the vehicle interior side W1, and the side sill inner panel 2 is formed in a cross-sectional hat shape opening to the vehicle interior outside W2.

サイドシルインナパネル２の側壁２Ｓの下端部の側面には、フロアパネル１４の車室外側Ｗ２の立ち上がりフランジ１４Ｆが溶接接合されている。そして、フロアパネル１４にフロアカーペット１３が敷かれ、サイドシルインナパネル２の上壁２Ｊと、側壁２Ｓと、側壁２Ｓに取り付けられたセンサ３とがフロアカーペット１３の車室外側Ｗ２の端部で覆われている。   A rising flange 14 </ b> F on the outer side W <b> 2 of the floor panel 14 is welded to the side surface of the lower end portion of the side wall 2 </ b> S of the side sill inner panel 2. Then, the floor carpet 13 is laid on the floor panel 14, and the upper wall 2J of the side sill inner panel 2, the side wall 2S, and the sensor 3 attached to the side wall 2S are covered with the end portion of the floor carpet 13 on the outside of the passenger compartment W2. It has been broken.

また、サイドボディアウタパネル６の上側フランジ６Ｆ１とサイドシルインナパネル２の上側フランジ２Ｆ１とでサイドシルストレングス７の上側フランジ７Ｆ１を挟み込んで３枚のフランジ６Ｆ１，２Ｆ１，７Ｆ１同士を溶接接合し、サイドボディアウタパネル６の下側フランジ６Ｆ２とサイドシルインナパネル２の下側フランジ２Ｆ２とでサイドシルストレングス７の下側フランジ７Ｆ２を挟み込んで３枚のフランジ６Ｆ２，２Ｆ２，７Ｆ２同士を溶接接合してある。これにより、サイドボディアウタパネル６とサイドシルインナパネル２とサイドシルストレングス７とで閉じ断面を形成している。   Further, the upper flange 6F1 of the side body outer panel 6 and the upper flange 2F1 of the side sill inner panel 2 are sandwiched between the upper flanges 7F1 of the side sill strength 7, and the three flanges 6F1, 2F1, 7F1 are welded together to form the side body outer panel 6 The lower flange 6F2 and the lower flange 2F2 of the side sill inner panel 2 sandwich the lower flange 7F2 of the side sill strength 7, and the three flanges 6F2, 2F2, and 7F2 are welded together. Thus, the side body outer panel 6, the side sill inner panel 2, and the side sill strength 7 form a closed cross section.

上記の側突用のエアバッグによる乗員保護手段では、センサ３は衝撃力を瞬時に正確に検出することができなければならず、そのためには、センサ３の取り付け個所の剛性が強くなければならない。そこで、サイドボディアウタパネル６と共に閉じ断面を形成する前記サイドシルインナパネル２の内面２Ｊ１，２Ｋ１，２Ｓ１に、サイドシルインナパネル２の剛性を上げるための縦に長いブレース７（補強部材７に相当）が溶接接合されている。   In the occupant protection means using the side impact airbag described above, the sensor 3 must be able to detect the impact force instantly and accurately, and for this purpose, the rigidity of the attachment location of the sensor 3 must be strong. . Therefore, a longitudinally long brace 7 (corresponding to the reinforcing member 7) for increasing the rigidity of the side sill inner panel 2 is welded to the inner surfaces 2J1, 2K1, and 2S1 of the side sill inner panel 2 that forms a closed section together with the side body outer panel 6. It is joined.

［ブレース７の構造］
図５（ａ）〜図５（ｄ）に示すように、ブレース７は、上壁７Ｊと下壁７Ｋと側壁７Ｓを備え、図４にも示すように、ブレース７の上壁７Ｊの上面７Ｊ１がサイドシルインナパネル２の上壁２Ｊの内面２Ｊ１に接合し、ブレース７の下壁７Ｋの下面７Ｋ１がサイドシルインナパネル２の下壁２Ｋの内面２Ｋ１に接合し、ブレース７の側壁７Ｓがサイドシルインナパネル２の側壁２Ｓの内面２Ｓ１に接合している。図５（ｄ）の斜線部はサイドシルインナパネル２の内面２Ｊ１，２Ｋ１，２Ｓ１に対するブレース７の接合部を示している。そして、図３に示すように、前記センサ３とサイドシルインナパネル２の側壁２Ｓとブレース７の側壁７ＳとがボルトＢ（締め付け部材に相当）で一体に共締め固定されている。 [Structure of brace 7]
As shown in FIGS. 5A to 5D, the brace 7 includes an upper wall 7J, a lower wall 7K, and a side wall 7S. As shown in FIG. 4, the upper surface 7J1 of the upper wall 7J of the brace 7 is also provided.

The hatched portion in FIG. 5 (d) shows the joint portion of the brace 7 to the inner surfaces 2J1, 2K1, and 2S1 of the side sill inner panel 2. As shown in FIG. 3, the sensor 3, the side wall 2S of the side sill inner panel 2, and the side wall 7S of the brace 7 are fixed together by bolts B (corresponding to a tightening member).

図２，図５（ｄ）に示すように、前記ブレース７の側壁７Ｓは、横断面Ｌ字形に形成された上下方向に長いＬ字形片８の一片で形成され、前記Ｌ字形片８の他片で形成されるブレース７の別の側壁７Ｈの上端部からブレース７の上壁７Ｊが車両後方側Ｒｒに延び、前記別の側壁７Ｈの下端部からブレース７の下壁７Ｋが車両後方側Ｒｒに延びている。   As shown in FIGS. 2 and 5 (d), the side wall 7 </ b> S of the brace 7 is formed by one piece of an L-shaped piece 8 that is formed in an L-shaped cross section and is long in the vertical direction. The upper wall 7J of the brace 7 extends from the upper end of another side wall 7H of the brace 7 formed in a piece to the vehicle rear side Rr, and the lower wall 7K of the brace 7 extends from the lower end of the other side wall 7H to the vehicle rear side Rr. It extends to.

前記サイドシルインナパネル２の側壁２Ｓは上側ほど車室外側Ｗ２（車幅方向外側）に位置するように傾斜し、前記サイドシルインナパネル２の側壁２Ｓの内面２Ｓ１のうち、ブレース７の側壁７Ｓが接合する被接合面部分２Ｓ２（図４参照）は鉛直面に形成されている。   The side wall 2S of the side sill inner panel 2 is inclined so as to be positioned on the outer side W2 (vehicle width direction outer side) as the upper side, and the side wall 7S of the brace 7 is joined to the inner surface 2S1 of the side wall 2S of the side sill inner panel 2. The joined surface portion 2S2 (see FIG. 4) to be joined is formed on a vertical surface.

前記センサ３は、ブレース７の側壁７Ｓの上下方向中央部に固定され、前記Ｌ字形片８の別の側壁７Ｈの上下方向中央部７Ｈ１（図５（ｃ），図５（ｄ）参照）は、前記別の側壁７Ｈの外面７Ｈ２の外方側に断面円弧状に膨出している。これにより、別の側壁７Ｈの上下方向中央部７Ｈ１の剛性をより強くすることができる。   The sensor 3 is fixed to the central portion in the vertical direction of the side wall 7S of the brace 7, and the central portion 7H1 in the vertical direction of the other side wall 7H of the L-shaped piece 8 (see FIGS. 5C and 5D). The outer wall 7H2 of the other side wall 7H bulges out in an arc shape in cross section. Thereby, the rigidity of the up-down direction center part 7H1 of another side wall 7H can be made stronger.

そして、ブレース７の側壁７Ｓの接合面とは反対側の面に第１ナットＮ１が溶接固着され、ブレース７とサイドシルインナパネル２の側壁２Ｓに前記第１ナットＮ１と同芯状のボルト挿通孔Ｓが形成され、ボルトＢがボルト挿通孔Ｓに挿通されて第１ナットＮ１に螺合している。図５（ｃ）に示すように、ブレース７の側壁７Ｓの上下方向中間部はブレース７の側壁７Ｓの上下両端部よりも前記別の側壁７Ｈとは反対側に突出して幅広に形成されている。   A first nut N1 is welded and fixed to a surface of the brace 7 opposite to the joint surface of the side wall 7S, and a bolt insertion hole concentric with the first nut N1 is formed in the brace 7 and the side wall 2S of the side sill inner panel 2. S is formed, and the bolt B is inserted into the bolt insertion hole S and screwed into the first nut N1. As shown in FIG. 5 (c), the middle part in the vertical direction of the side wall 7S of the brace 7 is formed wider than the upper and lower end parts of the side wall 7S of the brace 7 so as to protrude on the opposite side to the other side wall 7H. .

図２に示すように、前記第１ナットＮ１の近傍に位置するサイドシルインナパネル２の側壁２Ｓの内面２Ｓ１には、ハーネス１１のアース４の固定用のボルトが螺合する第２ナットＮ２が溶接固着されている。第２ナットＮ２は第１ナットＮ１の上側に位置する。   As shown in FIG. 2, a second nut N2 to which a bolt for fixing the ground 4 of the harness 11 is screwed is welded to the inner surface 2S1 of the side wall 2S of the side sill inner panel 2 located in the vicinity of the first nut N1. It is fixed. The second nut N2 is located above the first nut N1.

（１） ブレース７の上壁７Ｊの上面７Ｊ１がサイドシルインナパネル２の上壁２Ｊの内面２Ｊ１に接合し、ブレース７の下壁７Ｋの下面７Ｋ１がサイドシルインナパネル２の下壁２Ｋの内面２Ｋ１に接合し、ブレース７の側壁７Ｓがサイドシルインナパネル２の側壁２Ｓの内面２Ｓ１に接合しているから、サイドシルインナパネル２の上壁２Ｊや下壁２Ｋの側壁２Ｓに対する倒れを抑制することができて、サイドシルインナパネル２の剛性・強度を強くすることができる。 According to the above structure,
(1) The upper surface 7J1 of the upper wall 7J of the brace 7 is joined to the inner surface 2J1 of the upper wall 2J of the side sill inner panel 2, and the lower surface 7K1 of the lower wall 7K of the brace 7 is connected to the inner surface 2K1 of the lower wall 2K of the side sill inner panel 2. Since the side wall 7S of the brace 7 is joined to the inner surface 2S1 of the side wall 2S of the side sill inner panel 2, the collapse of the upper wall 2J and the lower wall 2K of the side sill inner panel 2 with respect to the side wall 2S can be suppressed. The rigidity and strength of the side sill inner panel 2 can be increased.

（２） また、重量の増加に関してはブレース７の重量が増加するだけであるから、サイドシルインナパネル２の肉厚を厚く設定する構造に比べると、重量の増大を回避することができる。
さらに、車体側面への衝撃力を検出して側突用のエアバッグを作動させるセンサ３と、サイドシルインナパネル２の側壁２Ｓと、ブレース７の側壁７ＳとがボルトＢで一体に共締め固定されているから、センサ３をサイドシルインナパネル２に強固に一体化することができる。
従って、車体側面への衝撃力を検出するセンサ３の機能を十分発揮させることができる。 (2) Further, regarding the increase in weight, only the weight of the brace 7 is increased, so that an increase in weight can be avoided as compared with a structure in which the thickness of the side sill inner panel 2 is set to be thick.
Further, the sensor 3 that detects the impact force on the side of the vehicle body and activates the side impact airbag, the side wall 2S of the side sill inner panel 2, and the side wall 7S of the brace 7 are fixed together by bolts B. Therefore, the sensor 3 can be firmly integrated with the side sill inner panel 2.
Therefore, the function of the sensor 3 for detecting the impact force on the side surface of the vehicle body can be sufficiently exhibited.

（３） サイドシルインナパネル２の側壁２Ｓは上側ほど車室外側Ｗ２に位置するように傾斜しているから、サイドシルインナパネル２の側壁２Ｓが車室内側Ｗ１に倒れにくくすることができる。これにより、サイドシルインナパネル２の側壁２Ｓの剛性を強くすることができる。また、サイドシルインナパネル２の側壁２Ｓの内面２Ｓ１のうち、ブレース７の側壁７Ｓが接合する被接合面部分２Ｓ２が鉛直面に形成されているから、サイドシルインナパネル２の側壁２Ｓに取り付けられたセンサ３が傾斜した状態になることを回避することができる (3) Since the side wall 2S of the side sill inner panel 2 is inclined so as to be positioned on the vehicle interior outer side W2, the side wall 2S of the side sill inner panel 2 can be prevented from falling to the vehicle interior side W1. Thereby, the rigidity of the side wall 2S of the side sill inner panel 2 can be strengthened. Moreover, since the to-be-joined surface part 2S2 which the side wall 7S of the brace 7 joins is formed in the vertical surface among the inner surfaces 2S1 of the side wall 2S of the side sill inner panel 2, the sensor attached to the side wall 2S of the side sill inner panel 2 It is possible to avoid that 3 becomes inclined

（４） ブレース７の側壁７Ｓは、横断面Ｌ字形に形成された上下方向に長いＬ字形片８の一片で形成されているから、ブレース７の側壁７Ｓが単に一片だけで形成されている場合に比べてブレース７の側壁７Ｓの剛性を強くすることができる。 (4) Since the side wall 7S of the brace 7 is formed by one piece of the L-shaped piece 8 which is formed in the L-shaped cross section and is long in the vertical direction, the side wall 7S of the brace 7 is formed by only one piece. As compared with the above, the rigidity of the side wall 7S of the brace 7 can be increased.
